How Many Liters of Engine Oil Does the Classic Sylphy Require?
3 Answers
The Classic Sylphy requires 3 liters of engine oil, specifically the original 5W30 grade oil. Between the 5W30 and 0W20 grades, the Sylphy tends to favor 5W30 due to its better low-temperature fluidity, making it suitable for lower temperature environments. The viscosity of engine oil changes with temperature, so it's crucial to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the vehicle. The latter number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be interpreted as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Classic Sylphy is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and collect the old oil in a pan until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the filler cap on the engine's valve cover, typically filling up to three-quarters of the oil bottle; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
I've owned a classic Nissan Sylphy for three to four years, and every time I change the engine oil, it takes about 4 liters. The mechanics always say it's specifically between 3.8 to 4.2 liters, but the actual amount depends on the car's condition. For example, if the old oil isn't completely drained, you might need to add less; if it's fully drained, you'll need to add the full amount. Too little oil can cause the engine to overheat and stall, while too much can increase pressure and damage parts, so checking the dipstick is crucial—just fill it to the middle mark. Don't skimp and use low-quality oil; synthetic oil is more durable. I change it every 5,000 kilometers, and the oil cost is just a few dozen bucks—good for the car and peace of mind. The Sylphy is a sturdy model; just pay attention to the oil level, and it'll run smoothly, even on long highway trips. The owner's manual also recommends starting with 4 liters, so following that won't go wrong.
I often do car repairs myself and have changed the oil for the Nissan Sylphy several times, with the amount fluctuating around 4 liters. The standard oil capacity for the classic Sylphy's 1.6L engine is approximately 3.9 liters, but it's accurate only after completely draining the old oil. First, add 3.5 liters of new oil, then run the engine for a minute or two to circulate it, and finally check the dipstick to adjust to the ideal level. Too much oil increases fuel consumption and noise; too little leads to insufficient lubrication, accelerating engine wear. Using 5W-30 synthetic oil is ideal for the Sylphy, and buying four 1-liter bottles is just right for convenience. DIY oil changes are simple and cost-effective, plus you can learn some auto repair knowledge to avoid being scammed. Regularly changing the oil filter is also important—doing both noticeably improves overall vehicle performance.
